CC Request (and Collab?): Functional Soccer Goal

Hi. I'm looking for someone who is willing to make a soccer goal and is willing to grant me permission to make it functional. I've tied my volley kick interaction to the soccer ball, but I'd rather much have it bound to a goalpost since that is more game immersive and realistic. 

I know there are a few decorative soccer goals but I've tried contacting their creators and received no reply for more than a month now. I don't feel comfortable using their work without permission. Hopefully someone is interested.
